Question: In a complete binary tree, what is the relationship between the number of nodes and the height?

Options:

Correct Answer: Height = log(n)

Solution:

In a complete binary tree, the height is approximately log(n), where n is the number of nodes.

In a complete binary tree, what is the relationship between the number of nodes and the height?

Step 1: Understand what a complete binary tree is. A complete binary tree is a type of tree where every level, except possibly the last, is fully filled, and all nodes are as far left as possible.
Step 2: Know that the height of a tree is the number of edges on the longest path from the root to a leaf node.
Step 3: Realize that in a complete binary tree, the number of nodes (n) and the height (h) are related. The height increases as you add more nodes.
Step 4: Learn that the maximum number of nodes in a complete binary tree of height h is 2^(h+1) - 1. This means that as the height increases, the number of nodes grows exponentially.
Step 5: Understand that if you have n nodes, you can find the height by using the formula h = log2(n + 1) - 1. This means the height is approximately log(n) when n is large.
Step 6: Conclude that in a complete binary tree, the height is approximately log(n), where n is the number of nodes.

Complete Binary Tree – A complete binary tree is a type of binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.
Height of a Tree – The height of a binary tree is the number of edges on the longest path from the root to a leaf.
Logarithmic Relationship – In a complete binary tree, the height is logarithmically related to the number of nodes, specifically height = log2(n) for n nodes.
